Okay; then where are the muzzle flashes from the 32nd floor where the windows were broken? There are none when the gun fire is going on but there is some down at the lower level where you say it’s a strobe light of some kind. A strobe from what? If the window is flat and we are looking up at it seeing a strobe then that strobe must be at a higher elevation. Is it attached to a helium filled balloon?
Apparently some of the windows do open a little. Not enough for a person to jump out but a little so people can get fresh air. Some people actually have phobias requiring a window to open even if it’s just a little.
Not every thing is a conspiracy. There is much we don’t know. Making up crap doesn’t help
